Before you paint a dresser, preparing the surface is the single most important step for a durable, professional-looking finish. Skipping proper preparation is the fastest way to end up with a chipped, peeling mess just weeks after you complete the project. Sanding removes the old finish, smooths out imperfections, and creates the necessary texture for the new paint to adhere correctly.
To achieve a flawless result, you need the right tools and a clear strategy. This process is not just about making the wood feel smooth; it is about ensuring the chemistry between the raw wood (or previous paint) and your new coat of color. By following a systematic approach, you can transform an outdated piece into a stunning focal point for any room.
Gathering Your Tools and Materials
Success begins long before you touch the dresser with sandpaper. Having the right equipment on hand makes the job safer, faster, and significantly more comfortable. You want to ensure you are prepared for each stage of the sanding process without interruption.
- Sandpaper (various grits: 80, 120, 180, and 220)
- Sanding block or a random orbital sander
- Tack cloth or a damp rag
- Paint stripper (if dealing with thick, old varnish)
- Safety gear (mask, goggles, gloves)
- Drop cloths or plastic sheeting
Removing Old Hardware and Protecting Surroundings

Before you even look at the wood, you need to protect the environment and disassemble the dresser. Pull out all drawers and remove the hardware, such as knobs, pulls, and hinges. Tape off any glass panels or delicate details that you do not want to sand.
Lay down drop cloths to catch all the dust. Remember that furniture sanding produces a significant amount of fine particulate matter. You will save yourself a massive cleanup headache if you contain the dust to one area of your home from the start.
Starting with Coarse Grit
Breaking Down the Old Finish
If your dresser has a glossy or shiny finish, you need to break that surface down aggressively. Start with a coarse-grit sandpaper, usually around 80 or 120. The goal here is not to polish the wood but to scratch the surface and remove the top layer of varnish or lacquer.
Work systematically, moving the sander with the grain of the wood. Avoid staying in one spot too long, as you risk burning the wood or creating uneven surfaces. If you are using a sanding block, apply moderate pressure; if using an electric sander, let the weight of the tool do the work.
Smoothing the Surface
Progressing Through the Grits
Once the old finish is removed and the surface is no longer glossy, you can move to the next phase. Switch to a medium-grit sandpaper, such as 120 or 150, to smooth out the scratches left by the coarse grit. This step evens out the surface and prepares it for the final stage of refinement.
Pay close attention to the corners, edges, and carved details where a power sander might be too bulky to reach. You may need to switch to sandpaper wrapped around a block to maintain control and ensure these intricate areas are smooth and free of old paint residue.
Final Sanding and Cleaning
Preparing for Paint
The last stage of sanding requires a shift to fine-grit paper, such as 180 or 220 grit. This step is what creates the tooth or grip that paint needs to stick to. Even though the surface looks smooth to the touch, microscopic pores need this final abrasion to accept the primer and paint.
After sanding, you must eliminate every trace of dust. Use a tack cloth or a clean, damp rag to wipe down the entire dresser. If you leave sawdust on the surface, it will show through the paint as bumps and blemishes, ruining the smooth finish you just achieved.
Troubleshooting Common Issues
Sometimes, the dresser reveals more than just outdated color; it might have deep scratches, water rings, or old glue lines visible through the veneer. It is acceptable to leave minor imperfections that add character, but deep gouges might need wood filler or putty to create a level surface.
If you encounter knots or sap spots, make sure you use an oil-based primer, as these areas can bleed through standard paint. Treating these problem areas during the sanding and priming phase ensures that the final paint job looks consistent and professional.
